IMPROVEMENT IN .ELEVATORS.

Specification forming part of lLetters Patent No. 131,895', dated October 1,1872.

To all whom it may concern:

Be it known that I, GHARLEs R. O'rrs, ofA Yonkers, in the county of Westchester and State of New York, have invented a new7 and useful Improvement in Guides for Elevators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this speciicati'on, and in Which- Figure 1 represents a side.elevation of an elevator with my improvement applied; Fig. 2, a sectional side elevation of the same in part .upon a larger scale; and Fig. 3, a horizontal section in part.

Similar letters of reference indicate corresponding parts throughout the drawing.

This invention relates to guides for passenger and other elevators, in which, to obviate noise and rattle or shake of the car between the upright `or guide posts of the hoistway guides or slides carried by the car or traveling platform, and capable of motion toward and fromithe guide-posts, are brought to bear upon the latter or against suitable surfaces connected therewith, and so that in the up `contact with the fixed uprights 0r grooved attachments connected therewith, whereby a uniform pressureof the guides or slides is 0btained under varied adjustments of them in or out, and consequently a much smoother y GAsE D.

' and steadier action secured than when said guides or slides are controlled by springs.

In the accompanying drawing, which forms guide-posts or uprights of the hoistway, each of which is provided with a safety ratchetrail, B, and with a grooved rail, O, for the guides or slides D, carried .by the car E, to move up and down within. These slides D are loose-fitting blocks shaped on their outer edges or faces to it the grooves of the rails C, and are arranged within boxes F on the carin such manner that they are restrained from vertical movement, except in common with the car, but are capable of easy motion in and out from the rails (J.v .Said slides or guides are kept in steady and uniform contact with said rails by means of Weighted levers, G, having their fulcrums b at back of the boxes F, and formed with toes, Which press against the backs of the slides. In this way a uniform pressure of the slides or guides against or within the rails is obtained in or during all selfadjustments of them in or out, which pressure may be increased or diminished by simply shifting the weights on the levers.

What is here claimed, and desired to be se-4 cured by Letters Patent, is- The combination'of the weighted levers Gr with the loose or freely supported slides D oi' the car, and the guide-posts A or rails C connected therewith, substantially as specied.
